Ashlesha Manish Pokale
Final-year Electronics & Telecommunication Engineering undergraduate at SVPCET Nagpur. Specialized in semiconductor device characterization with NGSpice (WEL Lab, IIT Bombay), digital logic & FSM synthesis with Verilog/VHDL on Xilinx FPGA, real-time Edge-AI NPU sensor fusion, and Siemens PLC / SCADA automation.
Bridging Silicon Physics, Digital RTL & Edge AI Systems
I am a final-year Electronics & Telecommunication Engineering student at St. Vincent Pallotti College of Engineering & Technology, Nagpur. My core passion lies at the intersection of microscopic semiconductor physics and macroscopic digital hardware realization. From characterizing sub-micron MOSFET transfer and drain curves in NGSpice, to synthesizing complex FSM architectures on Xilinx FPGAs, to deploying real-time multi-sensor Edge AI on ARM NPUs, I build hardware that is mathematically validated, power-efficient, and engineered for mission-critical reliability.

Indigenous Integrated Railway Track Monitoring System (ITMS)
Contactless Edge-AI Multi-Sensor Inspection Architecture for Indian Railways
Engineering Motivation & Research Innovation
Conventional track inspection in Indian Railways relies on manual physical foot-patrolling or exorbitant imported Track Recording Cars (TRC) that require track closure. ITMS introduces an indigenous, contactless multi-sensor edge inspection vehicle powered by an ARM Single Board Computer (Radxa Cubie A7A with 3-TOPS Vivante NPU) executing real-time Edge-AI defect classification alongside 6-axis IMU vibration telemetry and GPS/LoRa geo-tagged alert dispatch.
